### Function

# GLib timeout_add_full

#### Declaration [src]

    guint
    g_timeout_add_full (
      gint priority,
      guint interval,
      GSourceFunc function,
      gpointer data,
      GDestroyNotify notify
    )

#### Description [src]

Sets a function to be called at regular intervals, with the given priority. The function is called repeatedly until it returns `FALSE`, at which point the timeout is automatically destroyed and the function will not be called again. The `notify` function is called when the timeout is destroyed. The first call to the function will be at the end of the first `interval`.

Note that timeout functions may be delayed, due to the processing of other event sources. Thus they should not be relied on for precise timing. After each call to the timeout function, the time of the next timeout is recalculated based on the current time and the given interval (it does not try to ‘catch up’ time lost in delays).

See mainloop memory management for details on how to handle the return value and memory management of `data`.

This internally creates a main loop source using `g_timeout_source_new()` and attaches it to the global `GMainContext` using `g_source_attach()`, so the callback will be invoked in whichever thread is running that main context. You can do these steps manually if you need greater control or to use a custom main context.

The interval given is in terms of monotonic time, not wall clock time. See `g_get_monotonic_time()`.

This function is renamed to `g_timeout_add()` in language bindings.

#### Parameters

`priority`

  Type: `gint`

  The priority of the timeout source. Typically this will be in the range between `G_PRIORITY_DEFAULT` and `G_PRIORITY_HIGH`.

`interval`

  Type: `guint`

  The time between calls to the function, in milliseconds (1/1000ths of a second).

`function`

  Type: `GSourceFunc`

  Function to call.

`data`

  Type: `gpointer`

  Data to pass to `function`.

  The argument can be `NULL`.
  The data is owned by the caller of the function.

`notify`

  Type: `GDestroyNotify`

  Function to call when the timeout is removed, or `NULL`.

  The argument can be `NULL`.

#### Return value

Type: `guint`

The ID (greater than 0) of the event source.
